Subject Re: A question about RPC

i would love an IDL, plus that modern serialization frameworks such as
protobuf/thrift support versioning (although i still have issues with
different versions of thrift not working nicely together, argh why is that).
the only downside is perhaps that they are a little slower than writables.
